As per a post by u/noVa_realiZe on the r/Radeon subreddit, they were pretty satisfied with the results, as their PowerColor RX 9070 Reaper gained an uplift of 25% in synthetic benchmarks, and around 8-12% while gaming. According to testing done by u/noVa_realiZe, the performance gains from flashing the BIOS were immediately noticeable in synthetic benchmarks. In Cyberpunk 2077 at 1440p with a mix of ray-tracing settings, the undervolted stock card averaged 70 FPS. Not the first exampleBack in April, a similar attempt was made, where a community member at leading German website PCGH (PC Games Hardware) took an Asus Prime RX 9070 and flashed it with the Asus Prime RX 9070 XT vBIOS. This translated into a consistent 15-20% performance uplift in synthetic benchmark tests, while additional tuning and overclocking resulted in scores that outperformed the stock RX 9070 XT.
